The Basics
In this chapter you will learn:
1
how the electrical current in the heart is generated
2
how this current is propagated through the four chambers of
the heart
3
that the movement of electricity through the heart produces
predictable wave patterns on the EKG
4
how the EKG machine detects and records these waves
5
that the EKG looks at the heart from 12 different perspectives,
providing a remarkable three-dimensional electrical map of the
heart
6
that you are now able to recognize and
understand
all the lines
and waves on the 12-lead EKG
7
that trusting the EKG machine to interpret your patient’s EKG is
nothing but an invitation to trouble!
